|nitrogen fertilizer;[肥料]氮肥
氮肥(Nitrogenous Fertilizer) 是指一類以提供植物所需氮素(N)為主要養分的肥料。氮是植物生長發育不可或缺的大量元素之一,是構成蛋白質、葉綠素、核酸(如DNA和RNA)、維生素和許多酶的關鍵成分。施用氮肥的主要目的是補充土壤中氮素的不足,以滿足作物對氮素的需求,從而促進植物莖葉生長、增強光合作用、提高作物産量和品質。
根據氮素存在的化學形态和化合物性質,主要氮肥類型包括:
參考資料:
"氮肥(nitrogenous fertilizer)"是含有氮元素的一類化學肥料,主要用于促進植物生長。以下是詳細解釋:
核心作用 氮元素是植物體内蛋白質、葉綠素、核酸等關鍵物質的主要成分,直接影響葉片發育、光合作用效率和作物産量。缺乏氮素會導緻葉片發黃、生長遲緩。
主要類型
典型施用公式(以尿素為例): $$ text{施用量} = frac{text{目标産量需氮量} - text{土壤供氮量}}{text{尿素含氮量} times text{利用率}} $$
